TO ALL WHOM IT MAY CONCERN: v

Be it known that I, JEAN MICHEL FUCHS, of the city, county, and State of New York, have invented a new and useful Process of Manufacturing Albumen, of which the following is a` full,clear, and exact description, reference being had to theA accompanying drawing forming part of this specification, and in which- Figure 1 represents a sectional elevation of an apparatus, or details connected therewith or forming the same, in illustration of my invention, and

Figure 2 a plan thereof.

Similar letters of referenceindicate corresponding parts. Y

My invention relates to the manufacture of albumen from blood by a simple and novel process of treating the same, which may be thus described, in connection with the apparatus-shown in the accompanying drawing.

I take, for instance, Yblood as it is found at the slaughter-house, and puttingit in a tub or vessl, A, transfer the contents therefrom into or on to n sieve or drainer, B, which may be done by arrangingthe sieve over the tub,v and turning the latter, with the sieve, upside down, over, and so as to leave said sieve on or across a vessel, C, after which a loose ring, D, may be applied to hold the contents in place. The clotty mattei is then cut through and through in 'various crosswise directions, for the purposeof severing or shredding, as it Were, the veins, in order more perfectly to extract the albumen. The varied Huid-matter running from the sieve or drainer into the vessel C is then allowed to remain twenty-four hours, more or less, when a sliding or vertically-adjustable pipe, a, is lowered to run eti' the same into a vessel, E,'wherc it is further allowed to stand, say twenty-four hourshprior to (or the cleared portion of it) being again run of by suitably lowering` a. sliding or verticallyadjustable pipe, byso as to only draw off the fluid albumen or albumen-water, leaving the sediment behind itin the vessel E. The tub A, and vessels or parts B, C, D, and E, should all be made of or lined or faced with zinc, to secure that cleanliness by frequent washings which it is necessary toobserve, and to prevent thewadhcsion of old blood ,or matter that would a'ect the new, to the injury or deterioration of the albumen produced. As the albumen-water is decanted from the vessel E, it is allowed to run into a tray, F, which -should be made ot' glass, and not of zine, as the application of heat to which it is necessary to subject said tray would cause the chloride of sodium in the zinc to'injuriously aifect the albuuien. This tray, with its contents, is then removed to any suitable heating-chamber or device, and exposed to a temperature, for .twenty-four hours or thereabouts, of 65 Reauniur, (aforo or less,) and afterwards allowed gradually to cool, say for twenty-four hours longeiyto about 80 Reaumur, when it will be solidified, and in a condition ready to bottle or pack for the market or for use, as or for the purposes' albumen is ordinarily required.

It will be obvious that this, my improved process of manufacturing albumen, may be variously modified as regards the character of the vessels employed and periods for the performance of itsseveral stages, as also the temperature at which certain of the latter are conducted, but the descriptfion'herc .given illustrates in a -practical manner how this my improvement may be very successfully carried into practice.

iWhat is therefore here claimed, and desired to be secured by Letters Patent, is

'lhe process, substantially as herein described, of manufacturing or, extracting albumen from blood.

JEAN MICHEL FUCHS.
